Description

A BNC Female 4-Hole Flange Solder Connector (often referred to as a BNC panel-mount jack receptacle) is a 50-ohm RF connector designed to mount onto chassis walls, bulkheads, or PCB enclosures.Unlike crimp or clamp cable connectors that hold an entire coaxial cable assembly, solder-type flange connectors feature a rear solder cup, pin, or post terminal. This allows a direct soldered connection to an internal hookup wire, coax center conductor, or circuit board trace inside the equipment housing.Technical SpecificationsParameterSpecificationConnector GenderFemale (Jack)Mounting Type4-Hole Flange (Panel / Chassis / Enclosure Mount)Termination Rear TypeSolder Cup, Solder Pin, or Solder TabImpedance50 $Omega$ (75 $Omega$ variants also available for video)Frequency RangeDC to 4 GHzVSWR$le 1.15$ to $1.20$ (DC to 3 GHz)Operating Voltage500V RMS peakDielectric Withstanding Voltage$ge 1500text{V RMS}$Insulation Resistance$ge 5000text{ M}Omega$Body Material & PlatingNickel-plated brass or stainless steelCenter Pin ContactGold-plated beryllium copper / brassInsulator MaterialPTFE (Teflon) for high-temperature soldering resistanceKey Design FeaturesSolder Cup / Pin Terminal: Provides a solid electrical connection for hand-soldering jumper wires, micro-coax core wires, or direct PCB integration behind the panel.4-Hole Square Flange: Mounts flush to chassis walls using four small machine screws (typically M2.5 or #2-56). The flange provides low contact resistance grounding across the chassis surface.Heat-Resistant PTFE Insulator: Prevents the center pin from melting or shifting during soldering operations.Panel Weatherproofing (Optional): Many variants include an integrated rubber O-ring under the flange plate to seal against dust and moisture ingress into the enclosure.
